Product Description

The KWIKSET 258SQT-514S.STRKP is a single cylinder deadbolt featuring SmartKey Security re-keying technology, designed for residential exterior door applications. It ships as a complete kit that includes a 6AL latch and a strike pack containing square corner, round corner, and 5303 round corner full lip strikes. The low-profile Downtown Square contemporary trim gives the unit a clean, modern appearance. The assembly arrives in a matte black finish and is sold as a single unit.

This deadbolt is intended for residential exterior doors where a keyed single-cylinder deadbolt is required. The included strike pack with multiple corner configurations makes it adaptable to standard door frame preparations whether the existing mortise has a square or round corner cutout. The 6AL latch is included for a complete installation without sourcing additional hardware. This unit is suited for new construction installs and direct replacement of existing deadbolts on residential entry doors.
